FFT Plugin: Revamp the main code to rid it of 64-bit math. Use 32-bit kiss_fft_scalar because 16-bit integers are generally a poor choice for computation on-target. Simplify display code to speed it up. Add logarithmic frequency display (need keymappings, guessed on some). On dual-core, perform FFT on COP. Add some support function to fixedpoint.c. ... and stuff.

Fixed the problems on the new version of the fire plugin (so repush it), added new actions to the pluginlib_actions to fix the keymaps on the Sansa e200 for the clock and fire plugins. Also slightly simplified the metronome plugin's key mapping with those new actions.

Revert today's fire commits because it crashed all the targets I could test with (OndioFM, M5, C250). The plugin action conversion also caused problems (e.g. in a c200 sim which was working) I couldn't control flame type and movement and couldn't exit.

plugins code cleanup : moved the duplicated fixed point table loockup based sinus/cosinus functions to fixedpoint.c, removed the bmp size definition in the clock.c|-(useless as the size is already defined in a .h generated with every bitmaps ...)

Optimise EQ coef calculation routines for both speed and size. Move now unneeded fsqrt function to plugin fixed point library in case it'll be needed. Move all fixed point helper macros to dsp.h. Added FRACMUL_SHL macro to facilitate high-precision shifting of 64 bit multiplies and remove rounding from macsr in main thread to make this work as intended.
...
Tested quite thorougly, but as always, be careful with your ears.
